"...a material object only really exists for a subject, existence being synonymous with "definition," or "boundaries." In other words, something cannot exist unless it is in some way separate and distinct from everything else. But only a subject can define, bound, and delineate. Again, until there is a subject, there is only a vast sea of quantum energy.
For example, try to imagine what the cosmos "looked like" prior to a living being seeing it. Obviously, it didn't look like anything. It's a purely meaningless exercise, because sight is a property of eyes and brains. Not only that, but everything depends upon perspective, and there were no perspectives prior to the emergence of life. There was only "everything at once" from "all possible perspectives," which is indistinct from nothing at all from no perspective (again since existence requires definition and boundaries). ..."
